To f1.7/ i/'m/ii. it vim/y con/cern.:

Be it known that l. B nn'r B. Sos-mim, a citizen ot' the United States,residing at (.lhicago, in the conntwv ot Cook and State ot' Illinois,have invented a new and use'tul lmproveiiient in lVater-lurit vingApparatus, ot' which the Vfollowing is a specilication.

.\l v invention relates to an iiiiproveiiientiii that part ot apparatusVtor purifying water t'or industrial purposes` bv softening it withchemicals which proportions the tpiantitv ot' the chemical solutionemployed to the raw water to be treated.

M v primar)v object is to provide a construction ot' rotary valvedevice. to be actuated b v the power ot the llow to the' apparatus otlthe raw water to be treated to suppl)v to the water the properproportion ot' the chemical solution for treating il'.

"lo this end niv invention consists in the valve device combined withwater-softening apparatus` to produce the aforesaid result; and it alsoconsists in details otl construction and combinations otl parts, all ashereinafter described and claimed.

Referring' to the accompanying drawings, Figure 1 isa broken view inelevation, partly sectional, in the nature of a diagram, showingwater-softening apparatus equipped with mv improvement; Fig. 2. a brokenview showing the valve device in longitudinal section with the ports ot'the valvc` in one ot theirtwo operative positions', and Fig. 3, asimilar view ot' the same, showing the valve-ports in their otheroperative position.

1 is the valve device, comprising as its preferred construction(representei'l in Figs. 2 and 3) :i casing. containinga tapering boretormterminate. respectively, in the openings 3, -1, and and pipes 16 and17 terminate, respectively, in the openings 6 and T ot' the easing.

lVitli the valve S in the position represented in Fig. Q the ports 9 and11 areclosed b v the casing-wall, while the port 10 connects the pipes11 and 1G and the port 12 connects the pipes and 1T, and a halt-turn otthe valve in its seat to the position represented in Fig. 3 causes theport E) to connect the pipes 13 and 16 and the port 11 to connect thepipes 11 and 1T and brings the ends ot' the ports 10 and 12 against thecasing-wall to close them while the pipe l5 is out ot' coincidence witha valve-port and is closed bv the valve.

Fig. 1 shows a preferred manner ot' utilizing the valve device otl thedescribed consti'uction coiiperatively in two situations in awater-puritving apparatus. At ,18 is represented a precipitilting-tankcontaining bailleplates 1t), to which the water to be purilied in it isted at'ter being mixed with a suitable clieniicil solution, (say ot'linie or soda,) with a supply ot' the mixture, which in the arrangementillustrated is obtained from two similar mixing-tanks 2O and 21. A valvedcvice 1 is interposed between the precipitatingtank and themixing-tanks, with its pipes 13 and 15 discharging downward into thetank 18 and its pipes 16 and 1T respectively coinniunicating with themixing-tanks 20 and 21, while the pipe 1-1 serves for conducting to theapparatus the llow from an)Y suitable source (not shown) ol the rawwater to be treated. (.)n the stem end 22 ot' this rotar)P valve aresecured a pinion Z2-l and a sprocket 2f-1. A levei 25 is t'iilerlimedcentrally at 2(3 between the mixing-tanks to adapt it to be i'ocked onits Vt'iilcriim under the action ot' a weight 2T. movable, as byrolling, between stops Q8 Q8 on the lever near its opposite ends, and anarm 22) depends troni the lever and terminates in a segmental rack 30,engaging the pinion 23. ln the mixing-tanks 2() and 21, respectively,are the floats 31 and 32, each supported on an end ot the lever 25 b v abent arm 3?), sti'addling the edge ot' the tank. and pivotally connectedat its inner end with the float and similarly connected at its outer endwith the lever. Above the plane otl the mixing-tanks is supported aehemical-solution tank 34:, having ioiiriialed upon it a rock-shaft 35,carrying stirrers 36 36, depending into the tank,

and a belt-pulley 37. Below the solution-tank is supported another valvedevice 1, with its pipes 13 and 15X, (corresi'ionding with the pipes 13and 15 of the lower valve,) communicating, respectively, with themixing-tanks 2O and 21 and with its pipe 14X, (corresponding with thepipe 14 of the lower valve,) communicating with the solution-tank. Thepipes 16 and 17X, which correspond, respectively, with the pipes 16 and17 of the lower valve device, are each equipped with a liap-Valve 38 forthe purpose hereinafter explained, and each has a flexible section,preferably of rubber hose, 39, interposed between rigid sections of apipe, the upper sections of the pipes terminating in inwardly-openingcheckvalves 40 40 and being adjustably supported by clamps 41 4l onvertical rods 42 42, depending from the solution-tank. The upper valvedevice 1 carries on its stem end a sprocket 43, connected by a chain 44with the sprocket 24, and the pulley 37 is connected by a belt 45 with asmaller belt-pulley 46 on the stem end of the valve of the upper valvedevice 1.

The operation is as follows: Assuming, for starting, that the parts ofthelower valve device 1 are in the relative positions shown of the valverepresented in Fig. 3 and that the parts of the upper valve device arein relative positions shown of the valve represented in Fig. 2, rawwater flowing through the pipe 14, port 11, and pipe 17 enters the tank21 and eventually lifts the iioat 32 therein, with the result of raisingthe adjacent end of the lever 25 and causing the weight 27 to move uponit and assist in depressing it toward its opposite end. At the same timechemical solution iiows from the tank 34,through the pipe 14 and therespective valve-port 10, into the pipe 16 and flexible section 39thereof, fill-l ing the same to its check-valve 40 and closing thelatter by the pressure of liquid against it. Meantime turning the valveof the lower valve device 1 is proceeding with the movement of the lever25 on its fulcrum by engagement of the rack 30 with the pinion 23, andthe sprocket connection between the two valves simultaneously turns thatin the upper valve device until they occupy positions in their casingsrelatively reversed from those described, wherein raw water from thepipe 14 flows through the port 10 and pipe 16 into the tank 20, andsolution from the tank 34 discharges through the pipe 14X, respectiveport 11 into the pipe 17X and lits flexible section 39, filling the sameto its check-valve 40 and closing the latter by the pressure of liquid,and the contents of the tank 21 dischargeinto the precipitating-tankthrough the pipe 17, valve-port 12, and pipe 15. lith these ports in thevalve of the upper valve device in the positions represented in Fig. 8the contents of the pipe 16X above the dotted line at 47 dischargethrough the port 9 and pipe 13 into the tank 2O when the float thereinis down, and in discharging opens the respective check-valve 4() tofacilitate the flow and the respective Hap-valve 38 to vent the pipe 16and prevent siphoning of that portion of its contents below the line 47,and with the ports in the upper valve device in the positionsrepresented in Fig. 2 the contents of the pipe 17 above the dotted lineat 47 discharge through the port 12 and pipe 15 into the tank 21 whenthe oat therein is down, and in discharging opens the respectivecheckvalve 40 to facilitate the flow and the respective flap-valve 38 tovent the pipe 17X and prevent siphoning of that portion of its contentsbelow the line 47.

As will be understood in starting with filling raw water into, say, thetank 21, as described, the firstcharge of water in that tank willdischarge without the addition to it of any solution; but thereafterchemical solution will enter the tank 2O from the pipe 16 each time theiioat 31 descends, and the solution will enter the tank 21 from the pipe17 each time the float 32 is down.

Though the upper and lower valve devices are alike in all particulars,the ports in the upper valve may be of smaller diameter than those inthe lower one, because the quantity of the liquid which passes throughthe Lipper' valve is less thanthe quantity of the liquid which passesthrough the lower valve.

The flexible construction of the pipes 16 17X adapts them for regulatingthe proportion of the chemical solution to be fed to the mixingtanks,since by raising the pipes, which are held in their adjusted positionsby the clamps 41, the quantity to be discharged from them may beincreased, and by lowering them the quantity to be discharged may bedecreased, according to the particular requirement for the raw water tobe treated and the quantity thereof admitted for each charge into amixing-tank.

The number of the ports in the valve ofthe device 1 may be any that isdesired, thus one or more, without departure from my invention. Thus thevalve device may be used for the raw water alone or for the solutionalone and some other suitable proportioning means may be substituted forthe valve device in one position, and if only one diagonal port isprovided in the valve to connect two diagonally opposite openings in thevalve-casing obviously there can only be a passage of liquid in IOO onedirection through the valve in one of the Y acter described, thecombination with the precipitating-tank and a mixing-tank, of a valvedevice, a discharge-pipe leading' from an opening in the valve device tothe precipitating'- tank and a pipe connecting' another opening' in thevalve device with the mixing-tank` and a supply-pipe for the water to betreated leading' to another opening' in the valve device, 1
